assure是及物動詞,可接名詞或代詞(不可接that從句)作簡單賓語。
assure可接雙賓語,這時表物的賓語須由介詞of引出; 表人的賓語如置于表物的賓語后,則須由介詞to(而非for)引出,如置于表物的賓語之前,則不必搭配介詞。
assure后接表物的賓語時,可由that從句或動詞不定式充當(dāng)。
assure指“使……確信”，不是指“確信”，因此，在使用時要注意在前面加上助動詞。I am assured of his honesty. 我確信他很誠實(shí)。I am assured that he is honest. 不可以直接說I assure his honesty。
涉及到“保險(xiǎn)”時，我們習(xí)慣用insure，而不是assure，如insure her car。不過assure也有指“保險(xiǎn)”的意思，如assure her life指“為她保人壽險(xiǎn)”；
在指“確?！睍r，ensure的用法比assure更加普遍。His work assured him a degree of happiness. 他的工作確保給他帶來了一定程度的幸福感。His work ensured him a degree of happiness. 第二句的用法更為普遍。
Life assurance通常是指到了指定日期或死亡所支付的特定金額的保險(xiǎn)，而insurance通常帶一定的風(fēng)險(xiǎn)性，若是在指定的日期內(nèi)沒有死亡，過了那個日期死亡的話，是不會得到保險(xiǎn)賠償?shù)摹?
